Do you practice much the rowing exercices ( moving one point forward and throwing wrists forward/down, putting one point back and putting wrist back to side ).
I was told this is a misogi exercise good to get ride of excess tension in the shoulders, get ride of headache ( hang-over ), or develop better breathing.
This is the exercise you practice sometimes with someone holding both of your wrists, standing in front of you.

I`ll check the links you sent on fascia and tensegrity, thanks for your posts.
